Git commit 8ecd26dcf2f42b748fcf2ca8259a8588e624e4d0 by Thomas Friedrichsmeier.
Committed on 30/12/2019 at 13:40.
Pushed by tfry into branch 'master'.
Somewhat experimental: Auto-lazy-install RKWard R package
This is so we can support switching to a different (compatible) R installation without re-installation of RKWard.
Needed on Mac, will be nice to have everywere.
Needs testing.
